There is no video signal shown on the display. How do I fix this?
Our driver may not be installed or is out of date. Install the latest driver from StarTech.com’s website. The primary display adapter for the computer has an outdated or basic driver installed. Update the video driver using the manufacturer’s support site. The product requires an existing video controller (onboard or discrete) from Intel, AMD, or NVIDIA. The video controller must have a WDDM (Windows Display Driver Model), compatible driver. Most video controllers from 2008 or newer will meet this requirement. An incompatible operating system is being used (i.e., MCT based adapter and macOS). If using a Mac, we recommend exchanging the product for a DisplayLink based version. The display connected to the StarTech.com adapter is set to the wrong video input. Use the display’s on-screen display menu to select the correct input. The following only applies to computers running Windows 8.1 or older operating systems. USB video adapters and some USB docking stations use different chipsets (ex. DisplayLink/Synaptics, MCT, Fresco, Silicon Motion). They will not work together on the same computer. If you are running into problems trying to use multiple USB video products, please check our Tech Specs to determine which chipset each product uses. If they do not match, then they will not work together.

Why does one of my connected displays turn off when my USB video adapter is connected?
While the purpose of our USB Video Adapters are to add an additional video output to your laptop or desktop computer, these adapters still require some resources from your internal video card. On a small number of video cards, adding a USB Video Adapter can exceed the limit of available resources, causing one of the connected displays to turn off. As a possible workaround for this issue, we recommend using a more powerful USB Video Adapter that has a higher amount of integrated RAM, such as our USB32VGAPRO (512MB), USB32DVIPRO (512MB), or USB32HDDVII (1GB).

Will my touchscreen / all-in-one computer work with a USB Video Adapter?

Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not. All-in-One Computers Many all-in-one computer systems limit the number of possible monitors to one. This is a limitation in how all-in-one computers are typically manufactured, so adding an external display may not be possible regardless of which USB video adapter is used. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

Can I use a USB video adapter if my computer does not have a functioning graphics card or integrated graphics?
No. A USB video adapter requires a functioning graphics card (GPU) or integrated graphics controller. A USB video adapter cannot replace or function as the computer’s primary graphics processor. Explanation: USB video adapters, including USB-to-HDMI and USB-to-DisplayPort adapters, expand a computer’s existing display connectivity. They rely on the computer’s graphics hardware and drivers to output video and do not contain a dedicated graphics processor that replaces a GPU. To use a USB video adapter: The computer must have a functioning dedicated GPU or integrated graphics controller. The system must boot using the existing graphics hardware so the primary display is recognized before the USB video adapter can output video. The USB video adapter can use technologies such as DisplayLink to extend or duplicate the computer’s display. The latest drivers for the existing graphics controller must be installed for proper operation. If the computer has no graphics hardware, or the graphics hardware is not recognized, the USB video adapter will not output video. A USB video adapter is designed to add display connectivity to a computer with existing graphics capabilities. It does not replace or emulate a graphics card.

What is the difference between mirroring, spanning, and extending monitors?
Mirroring monitors means that you see the same thing on multiple monitors. Spanning monitors means that your computer interprets all of the monitors that are spanning as one giant monitor. You can see different things on each monitor, and your desktop, taskbar, Start menu, and background are stretched across the monitors. Extending monitors means that your computer interprets the monitors that you are extending as separate devices. You can see different things on each monitor, and your desktop background is displayed on each monitor. In general, video splitters can only be used to mirror monitors. If you want to extend your desktop across monitors, you need to make a separate video connection for each monitor that you are attaching. If you want to attach more monitors than your computer has video ports for, you can read about USB Video Adapters here: www.startech.com/AV/USB-Video-Adapters/ . If you are using a video card with a DisplayPort connection that supports DisplayPort 1.2 you can use MST hubs from StarTech.com to extend your desktop to each monitor.
